He was being attacked well before that.

If you are already being attacked - what better way that to fail publically. As a strategy, it does not mean he is or is not. It just means that nobody will believe anythinhg.

If you have a 300 million USD company... do you want people digging and looking into you?

it is also a good tax strategy. He left Au with zero tax owing... The tax people think it is fakle, write it off... wright wins on all fronts.
